Set Properties - Performance tab (Windows DS-Client)
This screen can appear in a wizard or a properties dialog box. It allows you to view and change the Performance settings for individual backup sets.
 
Maximum pending asynchronous I/O for a file
This is the maximum I/O operations the DS-Client will queue for each file from this backup set.
Use DS-Client’s settings
(Default) Uses the setting in the DS-Client Advanced Configurations > Category: Performance > Parameter: MaxPendingIOPerFile.
Use specific value
You can override the default and set a custom value that only applies for this backup set.
• This option is intended for high performance backup environments. You must be able to test the different settings to determine the optimal value.
• This is only useful if the target storage containing the backup data is fast and efficient enough to take advantage of the increased I/O.
• WARNING: Slower storage can suffer performance drops if this value is increased too much.
Read buffer size for backup
This option adjusts the internal buffer amount that the DS-Client allocates for reading individual files for backup.
Use DS-Client’s settings
(Default) Uses the setting in the DS-Client Advanced Configurations > Category: Performance > Parameter: FileReadBufferSize.
Use specific buffer size (KB)
You can override the default and set a custom value that only applies for this backup set.
• You must be able to test the different settings to determine the optimal value.
• WARNING: Slower storage can suffer performance drops if this value is not properly set.
